Firebase Auth: How can an admin impersonate a user?

[Smitop]

How can I, as an admin, impersonate a Firebase Auth user, and generate a valid token for a user, without actually being able to authenticate as that user?

[Kato Richardson]

Assuming that one has #access to a service account (i.e. a privileged backend service), then it's possible to sign a JWT token with that users UID, which would then be used to sign in on a client as that user.
